8: Pet Foods Pt2 Flashcards
grain consists of starch, germ, and bran; each of which individually provide
starch= energy germ= protein and fat bran= fiber
what does it mean to split ingredients
listing several components of something rather than putting them together as the first ingredient (ex:grain)
beet pulp is a source of
fiber (often firm stool)
what is tomato pomace and what does it provide
by-product of tomato industry (skins, pulp, seeds), source of protein, vitamin A and B, and Fiber. increases palatability in cats
spraying digest on to fat coated food is called
enrobing
which is better source of essential fatty acids: oils or fats
oils
why would feed additives be used
preservation, color, texture or palatability
why we would add antioxidants as a non-nutritive additive
prevent fat rancidity
what are humectants
non-nutritive additive that reduces water activity to make water unavailable for microbial use
how antimicrobials work as an additive to prevent bacteria/mold
change pH <7 (acidic)
palatabilty of cat food could be increased by spraying
acids (like phosphoric acid) onto food
what emulsifying agent additives (stabilizers and thickeners) do
prevent separation of ingredients or create sauce/gravy
additive that can reduce dust
mineral oil
each AAFCO trial requires how many d/c, and what age
8 per trial, at least 1 yr
how long AAFCO trials minimum must run
6 months (26 weeks)
how long and at what heat we pasteurize colostrum for calves (and why?)
145F for 30 min, this is longer than usual and at a lower heat because too high of heat can damage the antibodies
why we suspect that johne’s disease in ruminants and crohn’s disease in humans are linked
Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne’s disease, it contaminates food of animal origin, MAP is consistantly found in ppl w crohn’s (both also have similiar signs, epidemiology, and pathology)
why using melamine as a nitrogen source in sheep was found to be bad
produced fatal uremia in sheep due to crystals
when diagnosing an old cat with cognitive dysfunction syndrome it is important to first
rule out any other issues
t or f; uncooked food is more easily digested because it contains enzymes that cooking destroys
F; no all nutrients are eliminated by cooking. denatured proteins may be easier to digest. plant-based compounds more digestible when cooked. when carbs cooked, gelatinization occurs, increases digestibility
difference between rennet and rennin
rennet= synthetic milk coagulant rennin= natural milk coagulant in calves
grain free dog food has been linked to what issue
heart disease- canine dilated cardiomyopathy (DCM)
